Full‐Field Damage Monitoring in Architected Lattices Using In situ Electrical Impedance Tomography

Advanced Functional Materials, EarlyView.
In situ electrical impedance tomography (EIT) turns 3D‐printed, CNT‐infused architected lattices into full‐field damage‐imaging systems. Tunable Voronoi‐based geometries act as active sensing architectures, enabling conductivity maps to detect early‐stage damage and localise sequential ligament fracture before catastrophic failure.

Differential response to vibration of three forms of scoliosis during axial cyclic loading: a finite element study

BMC Musculoskeletal Disorders, 2019
Background Scoliosis is a serious disease that can affect all segments of society. Few studies have investigated the response to vibration of differing sinusoidal axial cyclic loading frequencies for different forms of scoliosis in the lumbar spine ...

Vibrational spectra and assignments of 1-chloro-2-iodoethane

, 1998
Raman and infrared absorption spectra of liquid 1-chloro-2-iodoethane have been obtained. Additional Raman spectra of 1-chloro-2-iodoethane in room temperature solutions with different solvents and at low temperature (77 K) in the solid state have also ...

Mechanics of Telson Ridges in Mantis Shrimp for Impact Analysis and Implications for Bioinspired Elastic Shell Designs

Advanced Functional Materials, EarlyView.
The mantis shrimp telson reveals how ridged biological shields control deformation under impact. Inspired by this architecture, telson‐inspired ridged curved shells transform ridge geometry and macroscopic curvature into bidirectional snap‐through, tunable stiffness, and enhanced hysteretic energy dissipation for multifunctional architected materials ...

Lewis Acid Site Engineering in MOF‐Derived Aluminum Oxide/Carbon Composites for Dechlorination of Waste Plastic Pyrolysis Oil

Advanced Functional Materials, EarlyView.
Controlled carbonization of an Al‐MOF partially decomposes its linkers, exposing coordinatively unsaturated Al centers within an oxide/carbon composite. The resulting Lewis acid sites, rather than surface area, govern organochlorine capture: the composite removes chemically diverse organochlorines from waste plastic pyrolysis oil, outperforms a ...

Cochlear traveling-wave interference under simultaneous acoustic and vibrational stimulation (Finite element simulations of multi-frequency conditions)

Journal of Biomechanical Science and Engineering
Sound reaches the auditory system through air conduction (AC) via the ear canal or bone conduction (BC) via vibrations of the temporal bone, and both pathways are often activated simultaneously in real environments such as trains and vehicles ...

Vibroacoustic Optimization Study for the Volute Casing of a Centrifugal Fan

Applied Sciences, 2019
A numerical optimization is presented to reduce the vibrational noise of a centrifugal fan volute. Minimal vibrational radiated sound power was considered as the aim of the optimization.
